NP-40 Fractionation and Nucleic Acid Extraction in Mammalian Cells

[Abstract]  This technique allows for efficient, highly purified cytoplasmic and nuclear-associated compartment fractionation utilizing NP-40 detergent in mammalian cells. The nuclear membrane is not disturbed during the fractionation thus leaving all nuclear and perinuclear associated components in the nuclear fraction. This protocol has been modified from Sambrook and Russell (2001) in order to downscale the amount of cells needed. To determine the efficiency of fractionation, we recommend using qPCR to compare the subcellular compartments that have been purified with equivalent amount of control whole ... [摘要]  该技术允许在哺乳动物细胞中利用NP-40洗涤剂进行高效,高度纯化的细胞质和核相关的分室分离。 在分离过程中核膜不受干扰,从而使核部分中的所有核和核周相关成分留下。 该协议已经从Sambrook和Russell(2001)修改,以便缩减所需的细胞数量。 为了确定分馏的效率,我们建议使用qPCR来比较已经用等量的对照全细胞提取物纯化的亚细胞室。
【背景】为了充分获得对细胞过程的理解,需要分离核和细胞质隔室。 有许多协议,甚至一些商业套件可用于帮助分离两个隔间。 然而,大多数需要高离心速度,产量差异甚至验证最终产品中的污染物量的方法也是很高的。 我们的协议在低速下使用小型台式离心机,以获得高纯度的细胞质提取物和核/核周组合相关隔室,以及数据分析,以验证污染物的百分比。 迄今为止,已经测试的细胞系是293T,HeLa和GHOST细胞系。 (Galvis,2014; Galvis等,,2014)。

Isolation and Analysis of Stromal Vascular Cells from Visceral Adipose Tissue

[Abstract]  The obesity epidemic is the underlying driver of the type 2 diabetes mellitus epidemic. A remarkable accumulation of various pro-inflammatory immune cells in adipose tissues is a hallmark of obesity and leads to pathogenesis of tissue inflammation and insulin resistance. Here, we describe a detailed protocol to isolate adipose tissue stromal vascular cells (SVCs), which enrich various immune cells of adipose tissues. These SVCs can be used to examine the population and activation status of immune cells by tracking their cell surface antigens, gene expression, and activation of specific ... [摘要]  肥胖流行是2型糖尿病流行病的根本驱动因素。 脂肪组织中各种促炎免疫细胞的显着积累是肥胖的标志,并导致组织炎症和胰岛素抵抗的发病机制。 在这里,我们描述了分离脂肪组织基质血管细胞(SVCs)的详细方案,其丰富了脂肪组织的各种免疫细胞。 这些SVC可用于通过跟踪其细胞表面抗原,基因表达和特异性信号通路的激活来检查免疫细胞的群体和激活状态。
【背景】过去几十年来,肥胖现在已成为一种流行病,已成为胰岛素抵抗最常见的原因之一。胰岛素抵抗是代谢综合征发病机理的关键病因。代谢综合征的延长状态推动了2型糖尿病(T2DM)的发展(Romeo et al。,2012; Johnson and Olefsky,2013; Saltiel and Olefsky,2017)。
   慢性低度组织炎症伴随着增强的免疫细胞浸润,是啮齿动物和人类肥胖症的标志,并且是通过促进炎症状态和中断胰岛素信号传导来促进胰岛素抵抗的发病机制的主要因素(Romeo等2012年; Johnson和Olefsky,2013; Saltiel和Olefsky,2017)。浸润的免疫细胞如促炎性巨噬细胞和B细胞在调节肥胖相关脂肪组织炎症和胰岛素抵抗中起关键作用(Weisberg等,2003; ...

[Abstract]  This is a protocol to detect HIV-1 reverse transcription products in cytoplasmic and nuclear fractions of cells infected with VSV-G-pseudotyped envelope-defective HIV-1. This protocol can also be extended to HIV-1 with regular envelope.
